The Grey Wolf, also known as the Gray Wolf, is a member of the Canidae family, a biological family of Mammals that include Dog-Like and

               Wolf-Like Carnivours and Omnivours. Wolves are believed to be a type of dog mutation. Grey wolves live in forests, deserts, mountains,

               tundra, tungia, grasslands, and urban ares. The Grey Wolf averages 85 lbs. and can be 4.3 to 6.6 ft. long and it can be 2 to 3 ft tall. 

               Grey Wolves are seen alone but most commonly seen in packs, that consist of at least 2 wolves but the average size of a pack is 8 wolves.

               Wolf Packs constantly searching for prey, walk through at least 9% of its territory everyday. 91% of wolf deaths occur at the borders of

               other wolf territories, mostly adults. Wolves kill prey by severing the windpipes but most prey survive when they stand their ground but

               if the prey run they decrease chances of surviving. When eating a prey there is a pack status; first the breeding pair of the wolves eat the

               heart, liver, and lungs; then the intermediate rank wolves; and lastly the lower rank wolves eat last. Wolves can eat up to 7-8lbs of food at

               a time and 29-33lbs if they're really hungry, wolves must also eat at least 1,500 kilograms (3,307lbs) a year. Wolves use scent markings to

               claim anything, Breeding Wolves use scent marking most often, mostly males, and urine-scent things with a raised leg stance (while all the

               other wolves lie down) to enforce rank and territory. A dominant wolf will rub its body against other wolves to ensure that they are in their 

               pack. Wolves have scent glands all over their bodies. A wolf can surprisingly live up to 2 weeks without food or water, because it's summer

               diet consist of vegetation and it drinks a lot of water. Wolves communicate through body language. To show dominance a wolf stands stiff

               and tall, its ears stand up, and curls its tail; then it stares then pins a submissive wolf. To show Submission(active) the wolf lowers iits entire

               body and lips and ears are drawn back. To show Submission(passive) the wolf rolls over and exposes its vulnerable spots and whimpers. To

               show Anger a wolf stands up its ears, its fur sticks out, and it is ready to attack if necessary. To show fear a wolf tries to look smaller. To

               show Defensive its ears flatten against its head. To show Aggression it snarls and is ready to attack. To show Suspicion it pulls back its ears, 

               narrows its eyes, and its tail senses danger points. To show Relaxation its tail points straight down and the wolf will rest on its side. To show

               Tension a wolf's tail points straight out and the wolf may crouch, as if it were going to spring. To show Happiness they wag its tail and rolls

               its tongue out just like a dog. To show that a wolf is hunting it will be tense, to tell if it is tense or not its tail will be horizontal and straight

               if it is tense. To show Playfulness it holds its tail high in the air and wags it. Wolves can also run 35mph and jump over 12 ft.
